The article describes a methodology for determining the deposition rate of particulate matter in relation to the operating conditions of the water-tube boilers operating in a dusty flue gas flow. The description of soot particles and the causes of their occurrence in the process of fuel combustion are given. The applied methodology uses criteria equations selected for the appropriate mode of particle deposition, and containing values depending on the deposition rate and diameter of carbonaceous particles, viscosity and temperature of combustion products. The methodology is considered on the example of the parameters of the operation of the KV-GM-0.8 boiler unit at rated power. The results of calculating the deposition rate of particulate matter in the combustion product stream with a temperature from 100 to 1100 °C are presented, where the diameter of solid particles, varying in the conversion from 0.01 to 0.35 microns, was taken into account during the calculations.
